This invention relates to a casement window, and particularly to a form of casement window that can be econom cally constructed, easily washed, and W111 be relatlvely water and weather-proof.

In the accompanying drawmgs which show an illustrative example of awindow ,embodying my invention, Fig. 1 ma perspective view of an upper 'and lower; corner of the window at the hinge slde; Fig. ,2 1s a sectional view of the lower corner shown in Fig. 1' taken from the outside of the window; Fig. 3 is a sectional view taken at right angles to the view shown in Fig. 2; Fig.4 is a sectional view through the two side,members or jambs of the window with the sash in fully closed position; Fig. 5 18 a view similar to Fig. 4 with the sash shown in the position ready to be swung open Fig. 6 is a. view of thehinge side of the window similar to the view shown in Fig. with the sash 0 m; Fig. 7 is a view similar to Fig. 6 wit the sash shown in the position to which itis moved for washing; Fig. 8 is a detailed elevation of the locking mechanism with the parts shown in full lines in position in which they appear in Fig. 5 and in dotted lines in the-position in which they appear in Fig. 4; F ig. 9 is a detailed' sectional plan view of the lower-hinge corner of the window'and also shows a form of sash adjuster. which can be used with my window;,Fig. 10 isa side elevation of the locking mechanism of the sash adjuster window away from the hinge, showing an alternative form of locking mechanism that maybe used, and Fig. 14 is a section on linef14 14 of Fig. 13. It may also be noted that Fig. 13 is -a section on line'1414 of- Fig. 14. p

' The window-frame proper'is made up of four S-shaped members, of'which the jamb members '2 and 3. are substantially identical, and the lintel and sill members 4 and 5 are likewise similar. These four members are welded together at the corners, and because of the fact thateach of these members has three. bends, the resulting frame will be very stiff. In practice I have .fou'nd that a Very satisfactory frame can be made if these members are bent from 12-gauge sheet metal. The window sash is primarily made up of four members, all of the same shape in cross section. The members at the sides are designated by the numerals 6 and 7. The member at the top of the sash is numbered 8, while 9 is the member at the bottom of the sash. These four members are welded together,'forming an opening to receive the glass 10. In the drawings, the glass 10 is shown as held in place by putty 11, but any other well-known .means may be used for this purpose. Attached to the inner faces of the sill and lintel members. 4 and 5 are two similar racks 12 which run all the way overto the hinge or pivot side of the windirection. Stirrups 16 are providedto hold the pinions 13 in-engagement with'racks 12. Shaft 15 is attached to side member 6 of the sash by twoplates 17 inwhich the shaft 4 is free to rotate. It is thus apparent that if the parts are in the position shown in Fig. 5 the sash can pivot about shaft 15 which will act as a hinge for the window. It may be noted, however, that as the axis of this hinge is nearer the center of the window than the extreme right hand edge of .the sash, a portion of the sash will swing in towards the room, whereas, the balance will swing outward. Inasmuch as the top and bottom members 8 and 9 which are part of the sash frame, extend respectively up and down so that they overlap members 4 and 5, itis necessary to 'cut away portions of these members to permit the hinged edge of the sash. to swing inward (see Fig. 6). Members exactly similar in size and shape'to when the handle 20 israised, a camming ac-- tached to members 4 and 5-so that when the sash is closed, these members will fill up the spaces left by the cutaway portions. These I members are designated by the numerals 18 and 19 (see Figs: 1 and 3).

- In Fig. 4, the window'is shown in closed position. It is to be noted here that aportion of member 6 overlaps the outer face of member 2; and therefore while the sash is in this position the window cannot be opened. Accordingly, I supply an operating handle 20 which as an incident to the unlocking of the window moves the sash from the position shown. in. Fig. 4 to thepositionshown' in Fig. -5.. This same handle likewise serves to reverse. the movement ofthe sash when'the window is closed.

The operating handle is attached to a plate. 21 carried by side member 7, and it is pivoted so that the handle can be raised into the vertical position or lowered to the horizontal 'positlon, .but movement, below the horizontal position is prevented by lug 22 which preferably is formed integrally with plate 21. A keeper arm 23 is permanently fixed at right angles to handle 20 and is beveled at its free end as shown at'24. As shown in Fig. 4, a portion of side member 3 is cut away to receive keeper 23, and within the side member 3 is attached a casting 25. This casting 25 has a flange 26 adapted to cooperate with the beveled portion 24 of' keeper23 to draw the sashtoward the room,

a and to'hold the sash in such closed position.

It also has a back portion 27 against which the outer edge of keeper 23 will. press, so that tion will be exerted to force the sash into the .closed position shown in Fig. 4. In order to provide for the lateral movement of the sash into the opening position, casting 25 carries an arm 26 on which is formed a pin 27. .When' handle 20 is pushed down into horizontal position, pin 27 will act as a fulcrum,'so that the sash will be moved into'the position shown in Fig. .5.

It is to be noted that the racks 12-are longer than is necessary to provide for, the above-described lateral movement of the sash. This is to permit the window to be easily washed. Assoon as. the sash has been swung. open to the point where side member" 7 is clear of frame member 3, side member 6 can be pushed over awayfrom frame member 2 until shafts 15 come to the end of stirrups 16. This movement may be of sufficient extent to provide an openingof 5 inches, for example, between side member 6 and jamb member 2. This is a large enough space .topermit one to reach through and wash the outside of glass 10. The sash is shown in this position in Fig. 7.

With this form of device I prefer to use a form of sash adjuster which will operate to operation is started. Various forms of sash adjusters may be used. for this purpose, the essential feature being that the adjuster shall be such that as the sash is swung in, a positive thrust shall be exerted tending to throw the hinged edge of the sash over laterally to the position shown in Fig. 5, but that provision be made, for slippage in the adjuster to permit the. sash to move laterally from the position shown in Fig. 5 to the closed position shown in Fig. 4. An illustrative example of one form of sash adjuster adapted for this purpose is shown in Figs.

'9 and 10. Here the adjuster comprises two pivoted to the bottom sash member 9. 'The member 28 carries a'ratchet casting 30 and 7 member 29 carries a similar casting 31.. A screw 32 passes through these castings. and carries a thumb nut 33. Ratchet casting 31 may, if desired, be permanently attached to member 29, but ratchet casting 30 is so arranged that it can slide on member 28 without turning. In order to limit this sliding movement, member 28 has a slot 34 .through which screw 32 passes. Members '28 and 29 may be made of such size that when screw 32 p is in the position shown in Fig. 9 relativeto member 28, the members 28 and 29 will have the same effective length. When this is the case, the points of attachment to the sill and sash should be such that they are approxi mately one above the other when the sash is in the position shown in Fig. 2. The win 'dow can be held open to'any desired extent by adjusting the angular relationship of members 28 and 29. When the window is to be closed, thumb nut 30 is loosened so as to permit the two ratchet castings 30 and 31 to rotate relatively to each other. Then as the sash is pulled toward the frame, screw 32- will take the Position in slot 34 shown in Fig. 9 where it is in contact with the inner end of this slot. As the window is pulled shut, this contact will insure the hinged edge of the slot 34 towards the free end of member v28 andnot interfere with the lateral movement of the sash.--

When the window is closed, it maybe .noted from Fig. 1 that shaft 15 is tightlyv jammed between members 2and. 6. -This PIOVldES an air 'seal along the hinge side of the sash. At the opposite side of the: sash,

member 7 is drawn in againstmember 3 because of the beveled shape of the end of keeper 23. In. order to arrange for a tight fit of the sash against the frame at the top and bottom, .I provide an adjustable lintel member 351' and a corresponding adjustable sill member 36. These members are attached to frame members 8 and'9'respectively by the useof screws which pass through slotted holes. The conta'ct" of the flanges of members 8 and 9 against the outer faces of In order to prevent the window from being 20. opened until it has been moved into the position shown in Fig. 5, I may attach to' member 7, preferably below handle 20, a

plate 37 provided with a hole 38 (see Figs. 13 and 14). A pin 39 is fixed at a corresponding position in member 3 so that when the sash is moved laterally from'the p'osition of Fig. 5 (which is also the position of Fig.

13).'into the position of Fig. 4, pin 39 will enter hole 38 and keep the window shut until the reverse lateral movement has taken place.

In Figs. 11 and 12 I show an alternative form. of locking device for the free edge of the sash, which will be particularly useful with tall windows. In this form the free edge is drawn against the frame by the lateral movement of the sash independent of the like action of the keeper. 23. It may be used either to supplement the action of the keeper, or the keeper may be made to move freely in its casting so that it serves only to force the sash back and forth laterally.

As shown in these figures, I'attach to sill member 5, near the free edge of the sash, a casting 40 which is attached to member 5 by screws which pass through slotted openings 41. Extending up from the base of casting 40-are two lugs 42 and 43 which are adapted to cooperate with a plate 44 attached to the underside of the horizontal portion of member 9. As the window is swung, closed, plate 44 will be guided .by the curvedouter 'faces of lugs 42 and 43 into the gap between these two lugs; then 'as the sash is moved laterally plate 44 will strike the rear face of lug 43'and owing to the fact that this face is inclined, the sash will be drawn in against thewindow-frame. It

may be noted that lug 42 is made of sufli-' cient depth so as to limit the lateral movement of plate 44 toward the opening position. This willserve to prevent the sash from being moved too far over which might cause the edge of the sash to rub against jamb member 3 as the sash is swung open.

It is 'to be understood that a similar casting and plate may be attached at theupper part of the .window part as described.

What I claim is: 1. In a casement window, a frame, a sash as well as to the lower movablelaterally in the frame, 'but-of sufficient size to close the opening in the frame, and p1vot mechanism connecting one side of the sash and the frame adapted to permit :the sash both to turn relatively tothe frame and to move laterally relative thereto. 2. A'de'vice as characterized inclaim 1,

in which the pivot mechanism is adapted topermit the pivoted edge of the sash to move in the frame a substantially greater distance,
